Speeding to one of the top GC games of all time!
It's a Dreamcast remake and it was probably the best Sonic game on the Dreamcast. In the good mode you play as Sonic, Kuckles or Tails depending on the level, it's the same thing with the bad mode, exept you play as Shadow, Rouge or Doctor Eggman. It also features a Choa garden and Nursery which acts a bit like Nintendogs, both teams can go there and it's a really cool add on!
All together in the good and bad mode there is a total of 31 levels, the good mode has 1 extra level. Once you've completed both good and bad mode, you get to 1 last level, this is a secret mission however and both goodies and baddies team up to take down Dr Eggmans Grandfather who is planning to destroy the world with the "Ultimate weapon" to get revenge on humans. In this level you play as every characterb and in the end you have one final boss battle, where you and shadow team up to tak down this "Ultimate weapon", and guess what? You get to play as SUPER SONIC and SUPER SHADOW in space where you fly around battling him in mid-air! After this battle something very sad happens and if your a fan of the Sonic series you will know exactly what it is. Sonic Adventure 2 battle also spawned it's own TV show named SONIC X, it occasionly shows on Jetix.
Sonic Adventure 2 battle is a very enjoyable Sonic game and in my opinion it's one of the best in the series so far. If your a fan of Sonic you must have this! 4 STARS! Sorry guys i would have wrote more but i pretty much explained everything in the first 2 paragaphs!
